As a leading enterprise in China's steel structure industry, Great Wall Heavy Industry has established an "industry-academia-research golden triangle" innovation system (collaborating with Tsinghua University Bridge Research Institute, Politecnico di Milano Structural Laboratory, and its proprietary BIM collaborative platform) to drive the intelligent and modular development of steel structure products. The company's core technologies include: 1) Parametric modeling technology enabling automatic compliance with international standards such as AS5100/BS5400, addressing complex environmental challenges like coastal corrosion in Australia and century-long fatigue loads in Europe; 2) Digital twin technology facilitating full lifecycle management from design to manufacturing and operation, with AI algorithms predicting maintenance needs; 3) Modular bridge design enhancing construction efficiency and flexibility; 4) Utilization of high-quality steel from international mills like Belgium's Bi

This article discusses the raw material assurance system developed by Great Wall Heavy Industry based on its core philosophy of 'material foundation and quality first.' Through cooperation with top international steel mills such as Belgium's Bilei, it strictly selects steels that meet international standards like ASTM and EN 10025 to ensure the safety and durability of steel structure products. The article highlights four core advantages: 1) Digital twin technology for full lifecycle management, adapting parametric modeling to AS5100/BS5400 standards; 2) A design team led by university professors adhering to international norms such as AISI/BS5400; 3) Modular design (such as the 321-type Bailey bridge and the 91-meter-span D-type bridge) to enhance construction efficiency; 4) An intelligent operation and maintenance system for fault warnings. In the future, Great Wall Heavy Industry will continue to deepen cooperation among industry, academia, and research to promote the intelligent up

This paper explores how Changcheng Heavy Industry promotes intelligent transformation in the steel bridge sector through the "industry-academia-research golden triangle" model (collaborating with Tsinghua University Bridge Research Institute and Politecnico di Milano Structural Laboratory). The article highlights that the company focuses on "intelligent design and manufacturing," integrating digital twin technology (based on BIM collaborative platforms) to achieve full lifecycle bridge management, optimizing designs and enhancing durability. Additionally, Changcheng Heavy Industry strictly adheres to international material standards (e.g., EN10025, ASTM) and welding procedures (AWSD1.5, EN1090) to ensure bridge safety. Moving forward, the company will continue to deepen industry-academia-research collaboration and digital innovation, providing smarter and more reliable bridge solutions for global infrastructure.
